STEAM-TURBINE.

To all whom it may concern 4 Be zit-known that I, CHARLES TV. DARE, a

citizen 4 of the United States, residing at Chicago, in the county of Cook and State of useful Improvement in stegm Turbines, of

which the following is a specification.

My invention relates to improvements in steam turbines and has for one objechto provid a new and improved form of nozzle,

. gui e passages and supports thereforand is illustrated diagrammatically in one form in;

.the accompanying-drawing, wherein- Figure 1 is a plan view with the parts in.

section; Fig. 2, a section along .the line '2:'? 'of Fig. 1; Fig. 3. asection along the line '3-3 of Fig. 1; Fig. 4, a section along the line H Fig. 1.

' Like partsare indicated by. like letters throughout'the several figures.

'binehous'mg A diagrammatically shown by the cap screw A The steam supply pipe A is carried in the housing A and registers with the passage A in the guide A. The nozzle plate A is rigidly fastened to the support A by the cap'screws A which env gage the housing A to hold the'whole in position. "The chamber A in the nozzle plate and open at the bottom thereof. registers with the passage A and communicates with the steam nozzle A. The nozzle A discharges angularly against the curved in firmly in position upon the. support forniing-the guide passage C having the large intake opening C opening The. passage C decreases gradually in cross sectional area fromthe mfikfi openlng C to the discharge opening 1}" and-thisdecrease in cross sectional area Specification of Letters Patent.

Illinois, have invented a certain nwand The nozzle and guide passage support A. -1S rigidly attached at one end to the tur-.

and the small discharge i for steam turbines comprismg a plate and a Patented Sept. 17, 1912.

is obtained both by decreasing the distance between the wall of the housing and the guide block (7 and by beveling otf the surface of the support as indicated at C in Figs. 2, 3 and l; and also by bending down the roof and by bending up the roof of the housing as indicated at- C to provide a consection and a plurality of grooves extending ther from and of lesser depth than and decreasing in depth from said groove.

2. A nozhle' and guide passage support for steam turbines comprising a plate and a curved groove therein of rectangular cross section and a pluralitv of grooves inclined thereto of lesser deptli than and increasing in depthfro'm said groove.

.3. A nozzle and guide passage support for steam turbines comprising a plate and a curved groove therein of rectangular cross section and a plurality of grooves extending therefrom and of lesser depth than and decreasing in depth from said groove said grooves being of rectangular cross section.

.4. A nozzle and guide passage support for steam turbines comprising a plate and a curvedgroove therein of rectangular cross section and a plurality of grooves inclined thereto of lesser depth than and increasingin depth from'said groove said grooves being of rectangular cross section.

5. A nozzle and guide passage supportfor steam turbines comprising a plate and a curved groove therein and a-plurality of grooves extending therefrom and of lesser depth than and decreasing in depth from said groove.

6. A nozzle and guide passage support for. steam turbines comprising a plate and a 'curved groove therein and a plurality of grooves inclined thereto of lesserfl depth than and increasing in depth from said groove. Q

7. A nozzle and guidepaissage support curved groove therein of rectangular cross section and a plurality of grooves extending therefrom and of lesser depth than and decreasing in depth from said groove and a removable guide passage mounted on said support an registering with said grooves.

8. A nozzle and gulde passage support for steam turbines comprising a plate and a curved groove therein of rectangular cross section and a plurality of grooves inclined thereto of lesser depth than and increasing in depth from said groove and a removable guide passage mounted on said support and registering with said grooves. Y

9. In a steam turbine a plate and a guide passage housing removably mounted thereon a guide -block Within said housing and mounted on said plate so as to form a 15 curved passage of constantly decreasing cross sectional area said plate having a groove beneath said housing of constantly. decreasing depth.
